SKATE.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed-October 23, 1909. Serial No. 524,259.

To all whom 'it may concern:

Be it known that I, JOI-IN NUTTALL, a citizen of the United States,residing at Chicopee, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Skates, ofwhich the following is a specification.

The present invention is an improvement in skates, and more particularlyin the slide bearing for the clamps proper, and prevents any lateralmovement thereof during their adjustment. In this way, all strain isremoved 4from the adjusting bolt, and in consequence, a freer movementof said bolt is insured.

The invention also resides in the construction of the clamps proper insuch a manner as to facilitate their cooperation with the holder inobtaining the results above enuv merated.

A practical embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a fragmental side elevationof a roller skate, showing the application of the invention thereto.Fig. 2 is a bottom plan view of the sole-plate, to which the clampholder is directly attached. Fig; 3 is a front elevation of the skate.Fig. i is a collective perspective view of the parts of the clampconsidered as a whole.

The trucks, wheels and their associated parts shown in the said drawingsmay be of any preferred construction, and hence require no individualdescription.

In the structure illustrated, the sole-plate consists of two counterpartsections 1 and 2 formed at their inner longitudinal edges with dependingfianges 3 and il. These plates are spaced apart to receive the centerbar 5 between their flangeswhich latter are riveted to said bar, asshown.

The clamp, as is customary, -is arranged slightly in advance of thefront axle. It comprises, essentially, a holder composed of a pair ofcounterpart members 6 and 7, and a pair of slides or clamps proper, 8and 9, these parts being illustrated in de'tail in Fig. 4. The holdermembers are of skeleton formation and each comprisesa pair of spacedparallel rails 10 connected at their inner ends by flat cross pieces 11.4The base portions 12 of each pair of rails project toward each otherfrom the inner or presented faces of said rails and are coincident inlength therewith. At their outer ends, said rails are provided withperforated lateral ears 13 which project in opposite directions and havetheir upper faces flush with the flat upper edges of the rails. Thelower portion of each cross piece 11 is cut away centrally as at 111-,and in addition there is formed in each cross piece a pair of openings15. The slides, or clamps proper, like the holder members abovedescribed, consist each of a single piece of metal the outer end ofwhich is bent upward and slightly inward so as to form a 16. The innerend of each slide terminates in a tongue 17 of reduced width, which isbent downward and folded directly upon itself, as shown. Through boththicknesses or folds ofthe tongue there is formed a threaded opening 18.The proportions of the holder members and slides with respect to eachother are such that the latter will fit between the pairs of rails 10with said sections are provided, the longitudinal edges of the slidesresting upon the pairs of shoulders 12. The tongues 17 project downwardbetween said pairs of shoulders, the intervening spaces beingsufficiently wide to aHord the tongues clear passage.

In positioning the various parts above specified, the two holder membersare arranged directly in alinement with each other, with the presentedfaces 'of the crosspieces 11 fiat against the outer faces of the plateflanges 3 and 1, and the upper faces of the ears 13 and the upper railedges flat against the under face of the sole-plate, the length of saidrails being` exactly equal to the distance between the flanges and theadjacent edges of the plate. (See Fig. 2.)

element is The aforementioned ears are fastened to the plate by rivets19 Vwhich pass through theperforations therein, while the two crossApieces are directly connected together by rivets 20 passed through theopenings 15 and through registering openings formed in flanges 3 and 4.

To move the slides toward and froln each other,V the customary adjustingbolt 21 is provided. rlhe end portions of this bolt are threaded inlopposite directions and eX- tend through the tongue openings 1S. Thecentral portion 22 of said bolt is of slightly reduced diameter, asshown, is plain or unthreaded, and passes loosely through the cut-awayportions 14 in the cross-pieces 11 and through similarly cut-awayportions of flanges 3 and 4. At one end the bolt terniinates in theusual key-engaging portion.

As a result of the above described position and arrangement of the partsof the clamp, it will be seen that there is provided, in effect, acontinuous holder, which perfectly supports the slides, irrespective oftheir position, and thus relieves the strain upon the adjusting bolt.Consequently, the manipulation of the last mentioned part or greatlyfacilitated. Also by reason of the fact that the shoulders and railsextend the entire length of the holders, the slides will be guidedduring their movements and held against lateral displacement at suchtime, this effect being furthered to some extent by the projection ofthe tongues through the spaces between said shoulders. Finally, theformation of the cross pieces 11 and their direct attachment to theplate flanges materially strengthens the holders and renders theirconnection with the soleplate more secure.

I claim as my invention:

1. The combination,'with a skate soleplate comprising a pair of sectionsformed at their inner edges with connected depending flanges; of a clampholder secured to the under face of said plate and composed of a pair ofalining members arranged on opposite sidesof said flanges, the innerends of said members being fastened directly to said flanges; and a pairof sliding clamps carried by said members.

2. The combination, with a skate soleplate comprising a pair of sectionsformed at their inner-edges with connect-ed depending flanges; of aclamp holder secured to the under face of said plate and composed of apair of alining members arranged on opposite sides of said flanges, saidmembers being provided at their inner ends With flat cross piecesdisposed directly against and fastened to said flanges; and a pair ofsliding clamps carried by said members.

3. The combination, with a skate soleplate having a depending centrallongitudinal flange, of a clamp holder secured to the under face of saidplate and comprising a pair of alining members provided at their innerends with cross pieces arranged directly against and fastened to saidflange; and a pair of sliding clamps carried by said members.

4. The combination, with a skate soleplate; of a continuous clamp holdersecured to the under face thereof and comprising a pair of separatelyconstructed counterpart members arranged in alinement with each otherand having their inner ends connected together; and a pair of slidingclamps carried by said holder.

5. The combination, with a skate soleplate; of a continuous clamp holdersecured to the under face thereof and comprising a pair ofseparately-constructed members arranged in alinement with each other andprovided at their inner ends with crosspieces, said cross-pieces beingremovably connected together; and a pair of sliding clamps carried bysaid holder.

6. The combination, with a skate soleplate; of a continuous clamp holdersecured to the under face thereof and comprising a pair ofseparately-constructed members arranged in alinement with each other,each of said members consisting of a pair of spaced rails having theirinner ends connected by a cross-piece and their presented faces formedwith supporting shoulders coincident in length therewith and projectingtoward each other, said cross-pieces being re movably connectedtogether; and a pair of clamps slidable in said holder and having theirside edges resting upon said shoulders.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN NUTTALL.
